“…An insular fossil assemblage might in truth be unbalanced because of preservational biases rather than sweepstake colonization, or through a combination of these factors. Moreover, rare species have a low chance of being included in the fossil record (McKinney et al 1996).…”

“…Discontinuous stratigraphic records-or even exceedingly long stratigraphic recordsmay register significant shortterm events, whereas long records can have the effect of averaging out many short term variations. Some species-those with less uniform distribution in the fossil record-may appear to be more rare than those that are more evenly distributed (McKinney et al 1996). Other difficulties can arise from a fossilbearing stratum with reworked (exotic) particles and fossils or when sedimentary structures and diagenetic overprints (post burial modifications) postdate its deposition, thus making its analysis more difficult.…”

A Multidisciplinary Approach to the Analysis of Multifactorial Land Mammal Colonization of Islands

A highly debated question that engages paleontologists, zoogeographers, and zoologists is how terrestrial mammals colonize islands. The question’s oversimplification and the subjective and partial responses to it have led to reductionist models. Insular faunas and fossil assemblages result from a complex interaction of geological, biological (in a broad sense), climatic, eustatic, taphonomic, and historical processes. Insular assemblages and their accompanying variables should be investigated on a case-by-case basis. In this article, we discuss not only common misconceptions and their potential origins but also the key issues that should be addressed when dealing with the colonization of islands by land mammals. We call for the implementation of multi- and interdisciplinary research programs and teamwork, involving paleontological, geological, and stratigraphic information; climatological factors; sea-level evolution; sampling and analytical biases; ecological, physiological, taphonomic, and environmental factors; behavioral characters and ecological preferences; genetics; phylogeography; densities of colonizing populations; and historical reports of human-mediated faunal introductions

“…The high number of rare species for molluscs and macroalgae have important consequences, not only for the sampling strategy in future studies, but also on the temporal variation of these communities. In fact, rare species have the highest ecological turnover (extinction1 immigration) and the highest evolutionary turnover (extinction/ speciation) (McKinney et al 1996).…”

Nine atolls were characterized in order to understand how physical factors control the species composition, diversity, and abundance of macrobenth~c (coral, mollusc, echinoderm, and algal) communities inside the lagoons. Only one region, the central part of Tuamotu Archipelago, French Polynesia, was considered, in order to minimise the variation due to regional factors between regions.The lagoons investigated showed a gradient of physical factors, providing various landscape configurations. The physical factors were surface area, abundance of pinnacles, degree of hydrodynamic aperture, and relative ~rnportance of passes In t h s degree of aperture. Macrobenthic communities were characterized by low diversity and strong dominance of a few mollusc or echmoderm species that generally occurred in lagoons without passes. Correlation analyses indicated that species richness increases with the surface area of the lagoon. Species richness of corals, echinoderms, and macroalgae was also higher in lagoons having numerous pinnacles. Canonical correspondence analyses revealed that the distribution and the relative abundance of coral, echinoderm, and macroalgae species were correlated to the relative importance of passes, whereas degree of aperture of the lagoon was also relevant for corals and molIuscs. The physical factors that control the processes of water exchange between ocean and lagoon, including passes, submerged reef flats, and spillways, influence the identity and the abundance of most macrobenthic species inside the lagoons.

“…For mollusks, 64% of the species identified in this study were observed at only 1 or 2 stations (47 % for sponges, 4 1 % for echinoderms, 38% for macroalgae, and 22% for corals). These results have important consequences not only for the sampling strategy in future studies, but also on the spatio-temporal variation of the communities, since rare species have the highest ecological turnover (extinction/immigration) and the highest evolutionary turnover (extinction/speciation) (McKinney et al 1996).…”

Spatial patterns of 5 components of the macrobenthos [corals, macroalgae, mollusks, sponges, and echinoderms) at 42 stations on 4 reef types were compared in Moorea Fifteen a b~o t~c and biotic factors were measured and included in Canonical Correspondence Analyses. Macrobenthic communities were dominated by corals and macroalgae. Two major gradients (along the bays, and from the fringing reef to the outer reef slope) were found for corals, macroalgae, and echinoderms. The gradients were realized at a small spatial scale in Moorea [less than 2 km from the fringing reef to the outer reef slope at 35 m depth), while the same type of variation occurs at a large spat~al scale (more than 100 km) on the Great Barrier Reef. Abiotic and biotic factors explained a large amount of the variance in sponge and coral communities, but less for mollusks and markedly less for macroalgae and echinoderms. Some of the factors identified in this study, such as depth, sand coverage, and algal coverage, have been also reported as controlling factors in other coral reefs. In contrast, the high abundance of sea urchins and its impact seem to be characteristic of coral reefs around Moorea.
